Stellar objects moving away from

shift toward the blue end of the spectrum
shift toward the red end of the spectrum
appear to be brighter than objects moving toward the earth
appear to be dimmer than objects moving away from the earth

Nothing special actually happens to the stellar objects themselves.

THE LIGHT FROM stellar objects that are moving away from Earth
appears to shift toward longer wavelengths (the red end of the spectrum),
compared with the wavelength it actually has when it leaves the stellar object.

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction 

Question 1 answer: make sure you eat healthy foods and excercise atleast once a day.question 2 answer: sometimes bullying . bullying lowers a persons self-esteem sometimes which can make them not care for themselves to much making them feel bad about there body structer. that or they just have a bad body structer and there family/doctor said its unhealthy how they eat.
